The Quick Read: A founder plans the interest-only period end on a $4,000,000 super jumbo loan by treating the recast date as certain and the refinance as optional: the balance is still the full $4,000,000 on that date, the payment is recalculated over the remaining term, and the real choice is to absorb it, pay down, refinance, or sell. Nothing about that date is a surprise, because the note fixes it on day one. What you control is how early you pick an exit and how much cash and documentation you have ready when you need it.
- Interest-only means no principal paid down, so equity grows only through appreciation or voluntary paydowns.
- Through select wholesale programs, subject to full underwriting, the portfolio program pairs a 40-year term with a 10-year interest-only window. The bank portfolio program uses 5- and 7-year fixed-period adjustables.
- Above $4,000,000, every file is reviewed case by case before submission, and that includes any future refinance.
- A refinance at the end is a new credit decision with new leverage, credit and reserve tests. Treat it as upside, never as the plan.
What Actually Happens on the Reset Date?
On the reset date, the payment is recalculated so the same balance repays over the years that remain. A fixed-rate note keeps the same rate and changes only the payment type. The balance has not shrunk, but the runway has, so the monthly obligation steps up.
The interest-only period is not a loan maturity. No lump sum comes due unless your note is a balloon structure, which is a different animal, so read the note to confirm which one you hold. In a balloon, the full balance is due at the end. In a recast, the loan simply starts amortizing.
Two structures dominate this size range across the wholesale network. They end differently.
| Feature | Portfolio program | Bank portfolio program |
|---|---|---|
| Typical build | 40-year term, 10-year IO | 5- or 7-year fixed-period adjustable |
| Years left to amortize | 30 after the IO window | Depends on the note’s term |
| Interest-only ceiling | Up to 85% LTV, 700 credit floor | 60% LTV |
| Loan size reach | To $6,000,000 | To $30,000,000 |
Those are ceilings through select wholesale programs, subject to full underwriting. At $4,000,000 the leverage ladder, not the interest-only ceiling, usually decides what you can borrow. On an investment property, the purchase ladder at $4,000,000 to $5,000,000 sits at 65% on review, with credit at 760 or higher for that leverage, through the portfolio program’s super-jumbo overlays.
On a primary residence the purchase ladder runs 75% up to $4,000,000, then 65% from $4,000,000 to $5,000,000 on the bank portfolio program. Every figure above $4,000,000 is case by case.
The tail length matters more than most founders expect. A 30-year note with a 10-year interest-only window leaves 20 years to repay, according to Scotsman Guide. A 40-year structure leaves 30, so the step-up is smaller.
Key Terms Defined
Interest-only (IO) period: the stretch of the loan where your payment covers interest only and the balance stays flat.
Recast: the scheduled switch at the end of the IO period, when the payment is recalculated to repay the balance over the remaining term.
Voluntary recast: a payment reset you request after a large principal paydown, which lowers the payment but does not restart the IO clock.
Fixed-period adjustable: a loan whose rate is fixed for 5 or 7 years and then adjusts, so a rate change and a recast can land together.
Seasoning: the time a lender wants between two events, such as buying a property and refinancing it.
What Does the Plan Look Like on a $4M Balance?
The plan starts by qualifying the post-recast payment, not the interest-only one. Picture a $4,000,000 balance with the interest-only period ending. Nothing was repaid, so the new payment spreads the full balance over the shorter tail.
Here is a modeled illustration, not a forecast. Assume your income, or your property’s rent, covers the interest-only payment at about 1.3x. Once principal joins, the same income could cover the payment closer to 1.0x. The exact drop depends on the rate and the tail length, which this article does not model.
Programs also differ on which payment they test at the start. Some programs in the network qualify you on the interest-only payment, which flatters the file today. Others qualify on the fully amortizing payment. A file that clears only at the interest-only payment may not clear at recast, so ask before you choose a property.
The OCC’s mortgage banking handbook calls payment shock after the interest-only period the primary borrower risk. It describes periods of three, five or ten years and says the post-IO payment amortizes the balance over the remaining term. It also notes that qualified mortgage rules prohibit interest-only payments, which is why this product lives in non-QM lending.
On an investment property, coverage is the number to watch. The ratio is monthly rent divided by the full monthly obligation: principal, interest, taxes, insurance and any HOA dues. Lendmire’s complete DSCR loans guide walks through that math. On a residence, the test is debt-to-income, which programs in this range typically allow up to 50%.
The Five Exits Compared
You have five realistic exits. Each one trades cash, certainty and cost differently.
| Exit | What it requires | Main risk |
|---|---|---|
| Absorb the payment | Income or rent that covers the new payment | Thin coverage if income is flat |
| Pay down, then recast | A large lump sum of cash | Cash tied up, IO clock not restarted |
| Refinance | New appraisal, credit, reserves | Value, credit or lender appetite changes |
| New IO loan | A program offering IO at your size | Case-by-case review above $4,000,000 |
| Sell | A buyer at an acceptable price | Market timing |
The CFPB lists three paths at the end of an interest-only loan: pay the balance in full, refinance if refinancing is available, or start higher payments that include principal. It also warns borrowers not to assume they can sell or refinance. That warning is the best one-line plan check you will read. A plan that depends on a refinance is a plan that depends on a lender.
Servicers do not extend the interest-only window. A new window comes only from a new loan. Lendmire’s piece Can a Cash-Out Super Jumbo DSCR IO Loan Reset Into a New IO Period? covers that route in depth.
A Founder’s Countdown Timeline
Start about 18 months before the date. Lenders look at income history, so documentation needs lead time. Here is the sequence that works.
- 18 months out: calendar the date yourself. Business-purpose loans do not carry the mailed reset notices that consumer loans do, so assume nobody will remind you.
- 15 months out: pull the note, the interest-only rider and the prepayment rider. Confirm whether you hold a recast or a balloon.
- 12 months out: run the post-recast payment against a conservative income or rent projection. Decide your preferred exit and your fallback.
- 9 months out: order a valuation and a rent schedule if the property is an investment. Check credit and reserves against the future refinance ladder.
- 6 months out: if refinancing, talk to a broker about which programs offer your structure at your size.
- 3 months out: apply, with the old loan staying in place until the new one funds.
Prepayment penalties interact with this calendar. Check whether any penalty period outlasts your planned exit. If it does, the cost belongs in the exit math.
Founder Income Complicates the Refinance
Founders usually refinance on a different income picture than they bought on. Traditional personal-income documentation understates income for many business owners, so the bank-statement path matters. Qualifying income typically comes from 12 or 24 months of personal or business deposits after an expense ratio, through select wholesale programs, subject to full underwriting. Business statements need at least 25% ownership.
Transfers from your own business into your personal account count at 100%. Twelve months captures a strong recent year, and 24 months smooths a lumpy one. Which is better depends on your trend. The bank portfolio program uses 12 months.
A liquidity event changes the plan. A sale of equity can fund a paydown, but business funds, gifts, unvested stock and cryptocurrency never count toward the asset paths. The assets-only path needs U.S. liquid assets equal to the loan plus closing costs plus sixty months of any net loss on other residential property. Retirement accounts count at 70%, or 80% at age 59.5 and up.
Reserves are the quiet constraint. Programs in this range typically want 9 months above $1,500,000, plus 2 months per additional financed property to a 12-month maximum. On super-jumbo files, cash-out proceeds cannot satisfy those reserves. Plan to hold the cash separately.
Where the General Rule Breaks
Several edge cases change the answer.
- Adjustable structures. On a 5- or 7-year fixed-period adjustable, the rate adjustment and the recast can stack. Confirm the dates and the caps in your note.
- Leverage at the refinance. You will not necessarily get your original leverage back. A rate-and-term refinance at $4,000,000 to $5,000,000 on an investment property runs 60% on review. A cash-out refinance runs 55%, with credit at 760 or higher.
- Interest-only at the bank program. That program’s interest-only figure is 60% or the band’s ceiling, whichever is lower.
- Credit floors. Above the super-jumbo line the floor is 700, and a credit event needs 48 months of seasoning.
- Property type. Rural property is out above $3,000,000, and second homes are one-unit only.

What If the Plan Fails?
The refinance can fail for three reasons: value, credit or lender appetite. A valuation shortfall lowers the loan you can take. A credit dip can push you into a lower leverage cell. And a lender may simply not offer interest-only at your size at that moment.
The sequencing rule protects you. Keep the old loan in place until the new one funds. Never let a payoff depend on a loan that has not funded. If the refinance stalls, your fallback is the absorb-or-sell path, so model it first.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Questions to Bring to Your Lender and Advisor
- Is my note a recast or a balloon, and when is the date?
- Did the program qualify me on the interest-only or the amortizing payment?
- Does any prepayment penalty outlast my planned exit?
- Which programs offer interest-only at my future balance?
- What reserves and documentation will the refinance need?
Frequently Asked Questions
Can I extend the interest-only period?
Usually not. The window is a term of the note, and a servicer cannot add to it. A new window comes only from a new loan with full underwriting, and above $4,000,000 that loan is reviewed case by case.
Will I get a notice before the payment changes?
Do not count on one. Business-purpose loans are not covered by the mailed reset notices consumers receive. Calendar the date yourself, at least 12 to 18 months out.
Is a recast the same as a balloon?
No. A recast starts amortization and the loan continues. A balloon makes the entire balance due at the end of the term. Read your note to see which one you have.
Can I pay down principal during the interest-only period?
Often yes, though the rules are program-specific. A large paydown can lower the payment on a voluntary recast, but it does not restart the interest-only clock.
Does a 40-year note mean 40 years of principal payments?
No. A 40-year note with a 10-year interest-only window usually leaves 30 years to amortize, according to Scotsman Guide. Programs differ on structure, so confirm the term sheet.
